BOLT-CUTTER.

SIECIFIGATION fcrmirg part of Letters Patent No. 285,868, dated October 2, 1583.

Applichtion filed June 20, 1883. (No model.)

To all whom it may concern Be it known that l, EDWARD AMELor'mrof Spencer, in the county of \Vorcesterand State of ltlassachusetts, have invented certain new and useful Improvements in Bolt-(hitters, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, and to the letters of refer ence marked thereon.

My invention relates especially to devices employed for cutting off the extremities of bolts after the nuts have been placed thereon, and has for its object the production of an instrument which shall be simple and cheap to construct, effective in operation, and not-liable to get out of order.

To attain this end my invention consists, cssentially, in a fixed anda movable cutting-j aw, the fixed jaw having one cutting-surface and the movable jaw having three cutting-surfaces or faces, said jaws being so arranged as to cut the bolt on each side at one and the same time, thereby rendering the operation of easy and quick accomplishment. The stationary cutter is stationed at the forward end of a main frame, slotted for its reception, and the sliding jaw is attached to a cutter-bar, also within the slot in the main frame, this cutter-barbeinglinked to two powerful levers pivoted upon the main frame, and bearing handles, whereby the device may be operated; and my invention also involves certain novel and useful combinations or arrangements of parts and peculiarities of construction and operation, all of which will be hereinafter first fully described, and then pointed out in the claims.

In the drawings, Figure 1 is a plan view of my improved bolt-cutter, and Fig. 2 is a reverse plan thereof. Fig. 3 is a plan view of the' movable cutter. Fig. 4 shows the peculiar shape of the cutting-edges of both jaws or cutters, and Figi 5 is a transvcrsal sectional view of the movable or sliding cutter at line a a of Fig. 3.

Like letters of reference, wherever they occur, indicate corresponding parts in all the figures.

A is the main frame, constructed of malleable iron. 13 is a slot through the center of the main frame. (3 is a cutter-jaw fixed at the forward en d ofthe main :trame,at the extremity of slot 1B. I) is a cutter-bar held in place in slot B, and bearing the 'movable cutter E, which plays in an enlargement of slot E, being held therein by a cap-plate, F. Apin, G, affixed to bar 1), plays in a slot, H, in cutter or jaw E, said cutter finding a secure bearing against shoulder (1 upon bar D when forced forward. Gutter E consists of a single piece of metal, the center whereof is cut or slotted, said cutterbei ng provided with a cutting-edge, a, transversely across thee'nd of the slot, and one, 6, at each side thereof, as plainly shown in Figs. 3, 4, and 5, said cutter striking the bolt upon three sides, the side edges, a cutting to a certain depth, the transverse edge e and the stationary cutter completing the severing of the bolt. By giving bar 1) a slight backward and forward movement when cutter E is set against a bolt the cutter is driven therethrough without drawing it from the out made by the first impression, as shoulder d strikes said cutter with considerable force,this movement being made possible by the arrangement of slot H in cutter E, and the pin G attired to bar D, said pin withdrawi ng the cutter when the handles J are thrown wide apart. Pivoted to bar D, by means of pins 12, are links I, which are again pivoted atz' to eccen tric projections upon handle-shanks J, said shanks being pivoted to main frame A by pins a. ShanksJ are provided with sockets, wherein wooden operating-handles K of any desired length may be inserted. Vith these handles the cutter is not only operated, but the user is enabled to reach a bolt in any locality. L is a stop to regulate the approach of the lllilll dles toward each other.

The several parts of the device are secured d, g, and i.

Having now fully described my invention, whatI claim as new therein, and desire'to-secure by Letters Patent, is

1, A bolt-cutter consisting of a main frame having a longitudinal slot wherein are located a stationary cutter or jaw having a single cutting-edge and a movable cutter or jaw having three cutting-edges, operated by means of a movable bar to which level-arms are secured, said arms being pivoted to the main frame, substantially as shown and described.

together and held in place by means of pins (1,

2. The combination, with main frame A, of y stationary cutter or jaw O, movable cutter E, I links I, shanks J, and handles K, the whole mounted upon bar D, and operating-handles combined and arranged to operate substan- J, linked to bar D, substantially as shown and tially as and for the uses and purposes shown 15 "described. and described.

3. The combination,with stationary cutter G In testimony that I claim the foregoing I and cutter or jaw E, having slot H, of bar D, having bearing-pin G, and having a shoulder, d, and links I, the whole arranged to operate substantially as shown and described.
